LOUIS W. WITZRY, 0F WATERLOO, IOWA, ASSIGNOR TO WATER-LOO GASOLINE ENGINE COMPANY, OF WATERLOO, IOWA.

Specification of Letters Patent.

Patented May 16,1916.

Application filed July 19, 1915. Serial No. 40,682.,

To all whom it may concern Be it known that-I, LoUIs W. WITRY, a citizen of the United States of America, and a resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Positively-Actuated Lu bricating Devices, of which the following is a specification.

My invention relates to improvements in positively actuated lubricating devices, and the object of my improvement is to provide a lubricating apparatus more particularly designed for the lubrication of the bearings of engine crank-shafts or the like, wherein the lubricating material is forced through the delivery devices of the apparatus in the proper amounts, and is then re-collected for re-use by suitable means being a part of the apparatus. This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in

which:

Figure 1 1s a vertical transverse section of the crank-casing of a crank-shaft and through my improved pump and lubricating device connected therewith. Fig. 2 is alongitudinal vertical section of the parts shown in said Fig. 1, with part of the crank-casing broken away.

Similar numerals of reference denote corresponding parts throughout the several views.

The casing 29 has bearing-openings for a rotatable shaft 30 provided with the cranks 31, and other bearings for the ends ofa camshaft 32 located to the rear of the shaft 30 and about in the same horizontal plane, and parallel therewith. The cam-shaft has a cam-wheel. 33 fixedly mounted thereon and adapted to actuate the contacting end of a medially-pivoted rock-lever 34, pivoted at 35, and whose other end is pivoted at 36 to the upper end of a pitman 8. The lower end of-said pitman is hemispherical and seated movably in a concave seat or socket in a block 7, the latter fixed .on the plunger or stem of a solid piston 5 which plays in the pump-cylinder 3. A compression-spr1ng 6 is coiled about said stem and. engaged between the block 7 and the top of the. pumpcylinder and therefore tends to yieldingly .push up the pitman and the arm of the rockof the lever in working contact with the cam-Wheel.

The cylinder 3 forms part of a casting 2, the upper part of which together with the cyllnder being passed through and fitted in a bear1ng-seat37 in the bottom of said caslng. Said casting has a channel 9 therein in communication between the pump-chamber 4 and the interior of the casing, said channel being controlled by a ballcheck-valve 11, and the end of the channel which'is located within the casing being protected by a tubular structure of netted' fabric to serve as a strainer for a supply of oil which is kept permanently in. the bottom part of the casing.

Another channel 12 is provided in said casting, and has an orificed screw-plug 15 inserted in its outer end, said plug communicating with a stand-pipe 16 while the other end of said channel communicates with the chamber 4, the entrance beingcontrolled by means of a ball-valve l3 kept yieldingly in position by means of a small relatively weak coiled spring 14. The stand-pipe 16 is carried up the outside of said casing 29 and Y bent horizontally thereover to communicate with the bore of a screw-plug 17, the latter inserted in a casting 27 to communicate with an 1nner tube 18, the latter being openat the top to deliver into an inverted glass receptacle or chamber 20 mounted on said casting and held by means of a clamping-disk 21 and the bolts 25. The casting 27 has a transversely extended basal. portion projecting .equally on opposite sides of the chamber 20 and whose cylindrical cavity 22 is in communication with said chamber by means of a passage 26. The elongated part of said casting has in its bottom near each end an orifice in which is seated a plug 23 trol the communication of This lubricating device is especially adapted for use on the engines of tractors, since the working of the oil as pumped and delivered from the upright tube 18 into the glass chamber 20 may be seen by the operator. The means shown are illustrative of the principle of my invention, which however I do not intend to confine to the precise elements shown, since the same may be varied without departing from the principles of the invention.

Having described 'my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. A lubricating device, comprising a crank-casing pump-cylinder in the bottom of the crank-casing and in communication with a supply of lubricant, a piston reciprocatory in said cylinder, a receptacle above the crank-casing and in communication with said cylinder, acheck-valve adapted to consaid cylinder with said supply of lubricant, and horizontally channeled distributing-means in communication with said receptacle and at each end with said crank-casing.

2. A lubricating device, comprising a pump-cylinder in communication with a supply of lubricant, a reciprooatory piston in said cylinder, a check-valve in'said cylinder adapted to control its communication with said supply of lubricant, a .vessel supported on a higher level than said pump, an open tube leading into said vessel, means of communication between said pump-cylinder and said tube, a channeled distributing device having equal area distributing nipples at opposite ends, and means of communication between said vessel and said distributing device. b

3. A lubricating device, comprising a cam- Wheeha pivoted rock-lever actuated by said cam-wheel, a cylinder in communication with a supply of lubricant, a piston in said cylinder, operative connections between said rock-lever and said piston, a check-valve in the communications of said cylinder with said supply of lubricant, a distributing device for lubricant in communication with said cylinder, and means for controlling the communication between said cylinder and said distributing-device.

4. A lubricating device, comprising a casing containing a supply of lubricant, a pump-cylinder in said casing in communication with said lubricant, a check-valve in the communications of said cylinder with said lubricant, a cam-wheel in said casing, a medially-pivoted rock-lever having one end contacting with said cam-wheel operatively, operative connections between the other arm of said rock-lever andsaid piston including yieldable resilient means adapted to retain said lever in working contact with said camwheel, a transparent closed top vessel supported above said casing, an open-top tube leading upwardly into. said vessel, means of communication between said pump-cylinder and the lower end of said tube, a check-valve in said communications, a relatively long horizontal distributing chamber mounted on said casing, said casing being orificed, like nozzles depending from said distributing device through the said orifices and being in communication with opposite ends of said device, and a conduit leading from said transparent vessel into the middle part of the'inner hollow of said distributing device.
